我的聊天应用程序遇到问题，我需要能够向特定用户发送私人消息，我能够选择该特定用户，但由于某种原因无法弄清楚如何发送私人消息。
您将在下面找到我的服务器的代码，请提供帮助：
var express = require('express');
var app = express();
var PORT = process.env.PORT || 8000;
var http = require('http').Server(app); // this is a node server that uses express as the boiler plate
var io = require('socket.io')(http); // socket! pass our server as a parameter to it
// use express static to expose a folder
app.use(express.static(__dirname + '/public'));
var users = [],
connections = [];
var onlineClients = {};
// Register events on socket connection
io.on('connection', function(socket){
connections.push(socket);
// console.log("connected socket", connections);
socket.on("disconnect", function() {
users.splice(users.indexOf(socket.username), 1);
updateUsernames();
connections.splice(connections.indexOf(socket), 1);
console.log("disconnected socket", connections.length)
});
socket.on("send message", function(data) {
// console.log(data);
io.emit("new message", {msg: data, user: socket.username});
});
socket.on("notify user", function(data) {
io.emit("notify user", {user: socket.username})
});
socket.on("new user", function(data) {
socket.username = data;
users.push(socket.username);
updateUsernames();
});
function updateUsernames() {
io.emit("get users", users);
};
socket.on("private", function(data, recipientName) {
var recipient = connections.filter(function (recipient) {
return recipient.username === recipientName;
})[0];
console.log(recipient.id);
console.log(data);
io.sockets.socket(recipient.id).emit("received private msg", data);
});
// socket.on("create room", function(room) {
// socket.join(room);
// io.sockets.in(room).emit('event', "hey wusup am in this room");
// console.log(socket);
// })
});
http.listen(PORT, function(){
console.log('Server started on port ' + PORT);
});

您的加入私人房间的客户端代码
<input type="text" class="form-control" id="user_email" placeholder="user_email" />
<button text="join room" class="btn btn-primary btn-block" onclick="a();"> Join Room</button>
客户端中的javascript代码
function a(){
io.emit('privatechatroom', {email:document.getElementById('user_email').value});
}
您在房间中添加用户的服务器端代码
socket.on('privatechatroom',function(data){
socket.join(data.email);
io.emit('res',{mes:"you are added"})
});
现在你可以给最近添加到这个房间客户端的那个人发私信了
function b() {
io.emit('sendmail', { email: document.getElementById('sender_mail').value, message: document.getElementById('message').value });
$('#message').val('');
}
/*serverside code*/
socket.on('sendmail', function (data) {
io.sockets.in(data.email).emit('new_msg', { msg: data.message });
console.log(data.email);
});
这是我对你问题的明确解决方案…
向特定客户发送消息（私聊）
我希望这对你有用Sue…
